BleedCubbieBlue.com has issued a breaking news update on its site, claiming that Cubs starter Rich Harden has been placed on the 15-day DL with what the team is terming a "mid-back strain".
With Carlos Zambrano coming off of the DL, it had been expected that David Patton would be offered back to his original club, since the seldom used relief pitcher was a Rule-5 draft pick and must remain on the Cubs' 25-man roster.
The move of Harden to the DL is retroactive to May 18. Randy Wells will start in his place Saturday night.
The site will post further details when they become available.
